The 2012 SLK-Class combines the comfort of high-end and high quality equipment with a touch of athleticism. At the same time, the new roadster is the most fuel efficient in its class that corresponds to segments of the security in mind. All weather driving pleasure - open or closed on weekends or daily trips - is based on the genes of the SLK. 2012 Mercedes-Benz SLK350 for sale in the United States in June 2011.
Dr. Thomas Weber, member of the Executive Council responsible for Group Research and Development Manager, Mercedes-Benz: "With the SLK, we offer a wide range of technical options to provide customers a personal choice among them is a row of the unique innovations .. Furthermore, the SLK is an excellent example of how impressive performance, comfort and elegant high environmental standards can go together. In the history of 125 years of the car, we have never experienced such great leaps in efficiency. Reduction in fuel consumption and driving pleasure even more - a formula, we surely become a reality in the SLK. "
Outstanding on all fronts
The best or nothing - this motto is at the heart of the philosophy of Mercedes-Benz, and the theme for the new SLK. Since the beginning of the Roadster has been designed to provide superior performance in all areas, and the engineers at Mercedes-Benz has taken care of this requirement into reality providing the attributes that provide the SLK roadster with a leading position in its segment. Among them are extremely compact dimensions combined with a generous interior with many useful features. Exceptional performance and sporty handling are also important features of the new SLK. The new SLK is also the safest roadster with its incomparable range of security features.
Dr. Joachim Schmidt, Vice President of Sales and Marketing, Mercedes-Benz Cars: "closely associated with the genes of the SLK is an exciting drive in any weather condition, open or closed, leisure or daily driving combining sporty nature the exceptional comfort and high-level appointments The new SLK is also .. sets a new standard in compact roadster with consumption and environment are concerned about a lot of excellent features and technical innovations to make another benchmark in its class - .. and no doubt the success of our brand SLK is a roadster with character, and not everyone wants it. "
Striking, athletic and elegant
The designers of a body as for the new SLK roadster, which emphasizes its classic proportions. Behind the long hood and compact cabin is a short rear overhang - the main attributes that characterize all the classic sporting Mercedes-Benz.
Professor Gorden Wagener, Head of Design at Mercedes-Benz: "The SLK carries on the tradition of the venerable Mercedes-Benz roadster, and exciting, it is the style points to come alive, the presence athletic, sculptural and also expresses the personality .. and sensuality. The same goes for the interior. materials of high quality, lovingly designed details and finishing a very exclusive atmosphere characterized mainly sport. "
Striking front-end
The first striking feature is an upright grille that has the look of the Mercedes-Benz. The grid focuses on the long hood and well proportioned and with its light-catching contour she is already thinking of the dramatic qualities roadster. The wide grille door Mercedes-Benz star in a leading position in Central and shows a strongly curved chrome spoiler on the front. Clear headlights complete the look of the new SLK and face resembles that of the legendary 190SL of the 1950s, which is considered by many as the original "SLK". However, designers do not only focus on the past, the front of the new SLK, they also deliberately created a strong visual link with the "Gullwing" the new Mercedes-Benz AMG SLS and the new CLS-Class.
The result of this impressive work meticulously detailed, is that despite the most striking, stiffer front and larger frontal area, Cd value is reduced to only 0.30 - a brilliant performance (CD value of the previous model was 0 32).
Dramatic Lines
The timeless, classic shaped side profile of the classic roadster proportions embody the aesthetics of the highest caliber and is a visual cue to the sportiness of the car and driving pleasure. Fine detail shows the care that was taken by the designers of Mercedes-Benz. For example, hide a tribe cast shared the sidebar does not interfere, as usual with the roof design. The vents in the front fenders with chrome spoiler, similar to the famous Mercedes-Benz roadsters of the 1950s. In the new SLK, they form the ideal basis for a characteristic line that goes to the rear wing muscles, using light and shadow to add aesthetics and timeless style on the sides. Meanwhile, the top edge of the large headlights - which for the first time, the LED technology - also seemed to float in the line of function.
This line is highlighted through the mirrors, which is located in the beltline, which allow a better visibility on the side of a very thin stems to match the car. Sophisticated aerodynamics also helps keep the side windows virtually free of dirt, while ensuring low noise of the wind.
Muscular rear
Rear eye is drawn to the integrated spoiler lip and broad tail light clusters. For the first time the tail lights with their horizontal design delivered across the LED technology. Their upper edge extends to the sides, culminating in the line function. A dual exhaust system with trapezoidal tailpipes complete the muscular impression.
Quality materials and elegant sportiness
Despite the more compact dimensions of its kind, the generous interior dimensions SLK 2012. To do this, designers have developed for the interior, providing driver and passengers the highest level of quality and precision. The interior is characterized by the elegant sportiness and faithful high quality materials that have been made with perfect precision and craftsmanship. Standard brushed aluminum trim covers the center console wood trim can be ordered as an option in gloss dark brown walnut. Four round metal output integrated into the dash to emphasize that this model really belongs to the family Mercedes-Benz sports car, their shape is a nod to them in the SLS AMG.
Echoing the exterior design, the black line emphasizes the horizontal lines and width of the vehicle. The SLK generous rings round the flank of a screen to the onboard computer. The color screen for the functions of communication and entertainment venues are located in the center console and is easily read by the driver and passenger.
Ergonomic multi-function sports steering wheel with leather rim and a flat bottom makes the nature of high-quality and sporty SLK constant tactile experience. Gearshift and metal decorating the races, and more sportiness and elegance. Inside can be further improved with the trim package, which includes wood / leather steering wheel and shift knob.
The scanning lines of the upper section of the dashboard continues in the door panels. The central panel of the door is color coordinated with the interior and door pulls and switches for seat adjustment are lined aluminum or wood option.
Sports seats and comfortable
The sporty, ergonomic adjustable seats with crash-responsive head restraints NECK-PRO integrated into the seat backs are high lateral forces and lateral support for maximum comfort on long rides. Convenience and comfort is provided by electrically adjustable with memory function and 4-way lumbar support.
Mercedes-Benz SLK350 offers a choice of Black Beige, Ash or the Sahara solar reflection in black leather and red sun and Bengali premium reflective leather, which greatly reduces heat generation. Leather has a special coating that reflects sunlight and measurements have shown that it reduces the temperature of the seats with more than 18 degrees Fahrenheit - a significant improvement in comfort when the car was parked in the sun.
As in the previous model, the AIRSCARF neck level heating system is optional for the new SLK. This creates a flow of warm air around the areas of the neck and shoulders of the occupants of a vent in the front of each head.
Lighting Attractive
An ambient lighting system available for the first time as an option in the sports package creates an impressive effect in the interior of the new SLK. It consists of discrete optical fiber in solar ROUGE, producing a comfortable and dramatic lighting in the door panels, door handles and around both sides of the center console. This improved the mood of the ambient light is activated when the doors open ("Welcome Home" effect), and its intensity can be varied individually by a dimmer.
The interior lights are in the central control panel includes two lights in general and the interior console and a projector. In addition, an LED on each pillar is to install more lighting inside and out.
Concept of intelligent storage
The new SLK offers an exemplary range of storage options provide versatility and usefulness of all days. Storage box has been enlarged by 26% over the previous model. In addition, the lid of the glove compartment includes useful features such as pen holders, credit cards and coins.
There are three storage compartments in the center console - under the command of air conditioning, two cup holders next to the COMAND in the center console and under the center armrest with a 12 V, USB and AUX (optional interface for integration of iPod media is available as part of the premium package). A network connected to the tunnel at the foot of the passengers has a flexible bottle cage that can safely accommodate up to 50 hp. oz bottles.
Great weather
The new SLK is equipped with a sensor anti-fog the windshield rearview mirror to record the temperature of the glass and the humidity level inside the new SLK. Dry weather, when not required for cooling, but / C works, steering down the compressor, but will be activated when it detects that the windshield is fogging. This has two advantages:
/ C mode can remain active all the time, but the demand controlled system to save energy.
As the air-conditioning only cools the air and demoisturizes which is necessary to maintain an internal temperature of the air is too dry can never undermine the comfort of passengers.
Innovative technology with a unique roof
Running a roadster is a very emotional experience, evoking images of cruising through the countryside with the sounds and smells of the outside, the top down and the sun shone. Wet weather has little influence since the SLK still has a retractable hardtop that transforms the roadster into fixed-roof coupe with a push of a button. Mercedes-Benz engineers have constantly refined the role SLK hardtop and maintained a pioneer in this technology.
Unique features: CONTROL OF MAGIC SKY
For the first time Mercedes-Benz offers a choice of three types of lightweight construction with retractable hardtop of the new SLK:
Standard roof is painted body color.
An optional panoramic roof with dark tinted glass.
The third option is a world first - the roof with panoramic CONTROL Magic Sky. This glass roof switching to light or dark transparent at the touch of a button. In light mode, it is almost transparent, with an outdoor experience, even in cold weather. Taken in its dark state provides shade and prevents inside heat from the sun. In other words, a pleasant touch of a button.
The first principle is based on the physics of a plate capacitor: If the glass structure is exposed to an electric voltage, the particles in the structure positioned so that light can pass through glass. If the voltage is still far, but the particles positioned randomly. This partially blocks the light and the glass is always dark. The controller and converter are integrated into the front of the roof and the switch is in the air control console.
The ultraviolet and infrared light is prevented in transparent mode, while further increasing the isolation clearly visible in the way of darkness, helping to maintain the temperature of the interior parts such as armrests cold as 18 degrees Fahrenheit report conventional tinted glass.
Measurements using a device called a pyranometer star Death Valley, one of the hottest places in the world, demonstrated the impressive effect. This device measures the intensity of exposure to sunlight. When you open the roof, the heat load heat of the sun in Death Valley reached 1000-1100 watts per square meter. With a transparent glass roof, fell to 200 watts, and when the roof had been moved to SKY MAGIC CONTROL darkened room, fell to 40-50 watts - an initial value of 20 and less than 60-watt bulb.
From the innovative glass also protects against the sun is much more efficient than conventional heat insulation glass and shutters, the occupants of the new SLK also enjoy the highest level of comfort climate. When driving with the roof open is unpleasant, due to intense heat, the driver and front passenger are able to relax under the sky roof Magic CONTROL - an important contribution to the comfort and security border of a typical driver-fitness Mercedes . Even when the vehicle is parked inside from overheating, as the roof is in the dark when the engine is off.
CONTROL Sky Magic is not only beneficial for passengers but also the environment as part of the trunk was taken by an air conditioning system, saving on CO2 emissions.
In addition, the three variants of the roof is now made of magnesium. This makes every roof around 13 pounds. lighter than the previous model, which gives the car a low center of gravity.
Engineers have also improved the operating mechanism for the roof and trunk lid. It is now less than 20 seconds to open or close the roof completely. The improved mechanism also creates a larger luggage compartment.
Completely agree on the trunk for everyday use
The luggage capacity is a retractable hard top closed is 10.1 cubic feet. Golf bag or a large suitcase is also a problem.
When the roof is open capacity is reduced to 6.4 cubic feet, enough room for two large sports bags, for example, with tennis courts.
To avoid a collision with the baggage of the elements of the top cover is loaded into the trunk, which can be rotated longitudinally. The roof can be opened if the lid is turned back, and when the roof is closed the lid can be swiveled forward with the hand for easy loading and unloading, and makes the trunk full capacity available.
The body structure with aluminum components
The body structure and good results in the previous model, and the weight is optimized for the new SLK yet. As a result, front fenders and hood are made of aluminum for the first time dashboards and between members and the rear, the rear wall module is a fiber reinforced plastic. The torsional rigidity of the lightweight steel structure has been optimized further enhanced by the intelligent use of lightweight construction methods, reducing the body weight about 29 pounds.
The doors are completely new, and reinforcements at the bottom of the belt line. Some of the high-strength steel side impact for excellent protection. A well-tested, welded to the column, in an oval-shaped steel tube high heat resistance and a nodular solid your side members will remain unchanged.
To keep repair costs down, the rays have a point before the court needed to repair a section, and the shape of the curves in front of the field in the event of a collision.
Aerodynamics copy
In addition to familiar features such as the spoiler at the top of the trunk lid spoilers wheel of the front wheels, and full engine compartment and underbody cladding, redesigned side mirrors and detailed changes in helped the column shaft to the excellent drag coefficient.
One of the pillars of the coating is a good example of meticulous development work. It took more than a year to develop a plastic that combines the strict design requirements with proper operation. The result is a pillar covered with a thin leading edge and upper surface drainage. This air flow ensures a very close and therefore a significant reduction in air resistance, air currents, aeroacoustics and dirt from the mirrors and side windows.
AIRGUIDE: innovative windstop
Convenient alternative to the traditional windstop AIRGUIDE has a new swivel, which was invented by Mercedes-Benz engineers in aerodynamics. This is a rotation of clear plastic shields that are mounted on the safety bars. Windstop This is the world's first comfort that allows for two different selected passengers. The driver and the passenger can rotate individually at the center of the vehicle units in time to tame turbulent flow without the installation or removal effort.
Headlights modern technology and LED bulbs
The SLK350 Mercedes-Benz is equipped with horizontally arranged LED daytime running lights four LEDs. The new SLK can be equipped with optional lighting package that provides the light curves of active functions.
The projector includes a range of active intuitive control that automatically adjusts headlamp beam angle change in the attitude of the vehicle - such as pitching during braking and acceleration - or to suit the vehicle load changes.
The large lights in the rear of the SLK new feature full-LED technology for the first time. This ensures not only a unique design at night, but also allows the LEDs to shine with different intensities in specific areas of the cluster light in the rear, depending on the lighting function. LED technology has other advantages over traditional bulbs, they light up about 0.15 seconds faster, and also has a shelf life considerably longer.
Sportsmanship and eco-efficiency
2012 SLK350 is powered by a revised V6 direct injection developing 302 hp/273 lb-ft. torque, the 3498 cm cubic displacement, using this power to accelerate to 5.4 (east) second 0-60 mph (top speed 155 mph). Its fuel consumption is an estimated 20 mpg city/29 Hwy allows 3 rd-generation direct injection, piezo injectors and a multi-spark.
Starting in model year, will SLK250 for sale, and the turbo four-cylinder direct injection engine delivers 201 hp/229 Nm of torque displacement of 1796 cc. SLK250 is equipped with a standard 6-speed manual, and consumes about 23 mpg city/31 Hwy From standstill, it reaches 60 mph in 6.5 seconds, and reaches a top speed of 155 mph.
The new V6 engine and new technologies
The six-cylinder engine is a part of the family of powerful new V6 direct injection engines. Known as direct blue, this innovation sets V engines from Mercedes-Benz as benchmarks in the world and made a further reduction in fuel consumption by 20 percent possible by structural changes alone.
V-angle of the new V6 engine is only 60 degrees. This allows the balance shaft for primary vibration to be omitted. As a result, the pilot noted a high degree of comfort. Carter, pistons and cylinder heads of the V6 is made of aluminum, while the crankshaft, connecting rods and valves are made of special alloys.
A new generation of engine technology includes many new construction projects, which are unique to one:
Multi-spark ignition and third-generation spray-guided direct fuel injection with piezo injectors to provide fuel economy in a homogeneous combustion process with a map of very widespread and fuel-efficient lean-burn technology.
The power consumption of additional units has been reduced. These include a water pump with a second optimized production management thermal oil pump on the application, a controlled volume of the fuel pump high pressure and a generator system of intelligent management.
Lightweight construction techniques and details of the improvements also reduce the friction of the engine significantly compared to the previous engine.
Third-generation direct injection system
Guided by a stream of gasoline direct injection (Mercedes-Benz, which was the first manufacturer to introduce mass production) is now in its third generation. The system pressure is 2901 psi and variable optimized for engine performance. New piezo injectors allow up to five injections per admission cycle for the formation of an optimal mix.
The crystal structure of the ceramic piezo-electric voltage changes less than microseconds, and the accuracy with only 1 / 1000 of a few millimeters. A key part of the nozzle piezo piezo stack, which directly controls the needle measurement. Whose response time is only 0.1 milliseconds, the fuel injection can be very easily and automatically adjusting the current load and engine, with a positive impact on emissions, fuel consumption and combustion noise.
In the V6 engine, multiple injections, even in very small amounts possible by piezo injection technology has been used by engineers at Mercedes-Benz to control a large, combustion process, effective use of lean operation.
Multi-spark for optimum efficiency
Third-generation direct injection system also has a fast multi-spark (MSI). After the first spark discharge and burning during the short, the coil is rapidly discharged and the second spark is discharged. MSI system allows up to four in a row sparks delivered in a millisecond, to create a larger spatial extension of the conventional plasma ignition. Control of this high-speed multi-spark, and to delay until the next ignition and burning time is adjusted optimally. This offers the versatility to optimize the center of the combustion and the residual gas, improving compatibility, specifically the use of stratified charge. Fuel consumption can be reduced by about two percent in this way.
Fuel savings of up to 4 per cent is only possible using a piezo-electric injection technology, along with several spark-ignition engines, depending on the freeway.
Setting new cylinder head with camshaft
Mercedes engineers have modified the variable, Vane hydraulic cam controls for intake and exhaust sides of the basic structure of the previous engine. Now they have a greater range of adjustment of 40 degrees relative to the crankshaft. Engineers were also able to improve the functionality, to reach 35 percent higher than the control of speed and adaptability is the oil pressure to the lowest level of 5.8 psi. Although the development of new features much smaller component size and light weight. For this reason, the installation space for the longitudinal and the vertical axis of the motor may be reduced by approximately 0.6 inches.
A two-stage low noise chain drive
The extremely small size of the cam controls reached a new, two-stage chain drive. The main chain units of two secondary chains - a bank cylinder, through the idler gear. All three chains can be adjusted separately using the chain tensioner. This leads to a low clamping force and dynamics of a small chain, ensuring consistent timing and excellent acoustic properties, which further reduces friction. In short, the new chain is compact and offers quiet operation.
Exhaust emission standards for strict
Exhaust systems on the SLK has been developed to meet the emission standards and noise standards ULEV. The exhaust system for 4-cylinder engine is made of a catalyst firewall, a quiet center and two rear silencer.
Emission control system for the V6 gasoline engine has a catalytic role in the firewall right and left cylinder banks. The exhaust gases then flow into the storage-type NOx catalyst. They are followed by a silent double center pipe and rear silencer designed as a silent reflection / absorption on the left and right by two and rounded exhaust.
Four-cylinder with a bite
Four-cylinder engine of the new SLK250 result of a reduction in principle, to reduce the displacement to compensate for a homogeneous direct injection and turbocharging. This leads to advantages such as weight reduction and reduce the friction of the engine. The smaller motor to move the field of operation of the combustion process towards a more favorable as a result of improvements in fuel consumption.
The system of direct injection four-cylinder has a maximum injection pressure of 2,031 psi. For the sake of greater efficiency, which allows higher compression ratio of a conventional port injection. The fuel evaporates directly into the combustion chamber reduces the temperature in the combustion chamber, reducing the engine's tendency to hit. The engine is homogeneous charge.
Turbine rotors are used to promote the creation of a four-cylinder engine. Is a single-flow turbo four-cylinder engine is more powerful than the mechanical charger, because it is the engine power is devoted to the rotors.
Other features of the four-cylinder engine is fitted with four intake valves and forged cam arrangement and adjustment of the exhaust camshaft is Vane-cell principle. This allows the valve timing can be adjusted quickly and continuously. The result is a high torque at low speeds, and higher than the individual results.
Carter and the cylinder head are cast aluminum alloy. The crankshaft is cast, and has eight counterweights. To compensate for the secondary masses inherent in a line four-cylinder engine, two rotating Lanchester balancer shafts in the crankcase at twice the speed of the crankshaft.
An electronically controlled thermostat allows the engine controlled warm-up (no coolant flowing through the cylinder when the engine is cold), and intelligent thermal management and thus shortened the heating phase.
Sports exhaust note
A sports exhaust note produced by a sound generator provides a background sound to the new 4-cylinder SLK250. This generator is located just off the accelerator components, and improves the exhaust sound with elements of income. It filters out certain frequencies of intake noise and takes the vehicle through a hose connection - a simple and ingenious and very effective for a sporty engine sound attractive.
Auto fuel economy benefits
The best seven-speed automatic transmission is standard on the Mercedes-Benz SLK350 (optional on the SLK250). The transmission has undergone extensive development to achieve a reduction of the torque converter slip, a significant reduction in internal losses and optimum efficiency. Mercedes-Benz developers to reduce vibration transmission by incorporating a new damper torque makes low-speed operation more comfortable.
ECO mode reduces the engine speed and fuel consumption improved significantly (up to seven per cent), but also provides a faster response to accelerator pedal movements. New hydraulic torque converter and optimized mapping also improves acceleration. In addition, fuel efficiency measures include a new transmission oil with lower viscosity and longer life.
The control unit optimized electro-hydraulic transmission, and new low friction materials in different parts of the transmission in combination with an optimized software results in better ride comfort.
Closer link with the road
This is the suspension that comes into contact with the road, ride comfort and agile handling depend on it. The new Mercedes-Benz SLK offers a choice of two versions:
A lowered sports chassis with harder springs and dampers provide a sporty driving experience systematic
An optional dynamic handling package is available as an option by special order. Its merits are an adjustable suspension with continuous damping. It has a fully automatic electronically controlled damping allows the vehicle to roll easily, even on poor road surfaces, but still offers high speed driving
Wheel position is the same for all three suspension options: 3-link front suspension is looking wheels, while the back of this suspension is an independent multi-link, which has already been demonstrated impressively unique position the wheel of the properties in the model previous year. The new SLK-Class, this is a forged aluminum hub carriers to minimize unsprung mass handling even better. All models of the new SLK is also a torsion bar stabilizer, which is connected directly to the frame.
Sports suspension is configured stiffer shock absorbers, suspension springs and stabilizers shorter torsion bar, with larger cross-section. The suspension is also reduced by 0.39 inches. Roll control system was established to get even smaller roll angle when cornering speed.
Suspension damping continuously variable automatic
The suspension damping automatic, continuously variable, which is included in the management option of dynamic packaging sets new standards. It provides a sporty and agile for maximum driving pleasure on winding roads in the country. An electronic system automatically and continuously ensures that the buffers are always made in response to the driving situation. The response time is usually about 10 milliseconds.
Establish the basic characteristics of the suspension is always to the left of the driver, however, with a switch that lets you choose the damping characteristics comfortable or sporty. At the touch of a button, so you have a suspension set available, providing comfort or sport settings. If you choose the value of sport, opted for a driving experience with a very high dynamic response.
As a sports suspension, suspension with varying degrees of attenuation is equipped with torsion bars a larger cross section, and the suspension was reduced to 0.39 inches.
Brakes pleasure of sporty driving
The test, dual circuit hydraulic brakes and the distribution of the two circuits for front and rear axles was adopted from the previous model. All variants are equipped with a piston floating caliper brakes everywhere.
Brake covers the front axle has been optimized for the wind tunnel, even more efficient cooling of the brakes and wheel bearings, brake discs and protect from road debris.
Electronic Parking Brake
Electrically operated parking brake in the new SLK will help in planning a generous interior. The switch is located under the dash light switch. Pressing plays electric parking brake, and then drag it to give up. Automatic transmission models, the brake is released automatically when the engine is running, the transmission is in position D or R, the driver is attached to the belt and the accelerator is pressed.
Straight and comfortable - the SLK Control
2012 SLK-Class features hydraulic-assisted Direct-Steer, which increases the agility and maneuverability, SLK, and improve the comfort of parking, less steering effort. It combines these attributes is a predictable and sure steering characteristics at high speeds. Consequently, agile roadster in the corners even more taste and accuracy, allowing for relaxed cruising on motorways, and is even more exhilarating driving pleasure.
The new Direct-Steer system was developed from the familiar speed-sensitive steering that Mercedes-Benz offers many of its models. This system is based on efforts to manage the speed of the vehicle - the effort required increases with speed. In practice, this means more comfort control during parking maneuvers and more safety at high speeds, for example, on roads safer steering ensures straight-line stability.
The new direct steering to maintain these positive characteristics as a function of speed and steering control to a more variable ratio that turns the steering angle. The ratio is indirect when the control is centralized, which ensures good straight-line stability and, therefore, a high level of security. Unlike other control variable, the ratio of Direct-Steer system is growing rapidly, when the angle of rotation of 5 degrees, the very direct steering angle, 100 degrees. Only a relatively small steering movements are also needed to repair the course.
During city driving with driver to steering movements less pronounced, making the change of direction as possible with less effort. Direct-Steer is even more impressive on winding roads, where only small steering movements are sufficient to steer the vehicle. Tight bends, the driver's hands have little to change their grip on the wheel. Rapid sequence of turns can be controlled almost intuitively, securely, accurately and enjoyable.
Despite its remarkable performance is the key element in the Direct-Steer system is simply a director. The secret lies in the teeth cut into it: in the middle of these teeth are slightly wave-shaped, with different profiles sides. In addition, the outer teeth are positioned at varying distances from each other so that the change in the ratio of management is produced by purely mechanical means. With this solution, Mercedes engineers were able to abandon the actuators and sensor complex systems used by other variables operating systems. Benefits include very low complexity and weight. The system always reacts in a predictable and constant, while operating systems other variables may need a quick adjustment of the driver rapidly changing situations.
ECO servo pump reduces fuel consumption
Straight in the new SLK also means saving fuel. This is ensured by the pump ECO power steering is standard on all SLK models. The middle section is electrically activated solenoid proportional valve that opens in various bypass hole is compressed connection to power the control unit with the right amount of liquid. Since the control is less energy when driving straight ahead, the pressure control can be minimized, and less energy is consumed.
Safety technology
The 2012 Mercedes-Benz SLK sets new safety standards in the roadster segment. Security experts have adhered to the motto "The best or nothing", invented by Gottlieb Daimler. Far from being satisfied with the achievement of scoring, to work hard to achieve a security level that far exceeds the standards required by regulators around the world. The most important work is the installation of laboratory test or an accident, but accidents real real life. They call the results of its security work in real life, a concept that is based on research by thousands of accidents. Using this irrefutable evidence, the engineers at Mercedes-Benz has developed or initiated the majority of which now support systems to effectively support the drivers and have been adopted by many competitors of the company.
ATTENTION ASSIST and adaptive brake standard
The new SLK is also a unique combination of driver assistance systems that help prevent accidents such as drowsiness detection system ATTENTION ASSIST. With this system, the roadster to develop a precise sense of the level of the driver's level of attention and can provide the alarm overtiredness.
Other standard equipment includes Adaptive made of ABS, ASR traction control and active yaw control system (GMR). It also includes the following features:
supported by the driver when accelerating uphill at a dead end, which prevents the vehicle rolling backwards unintentionally;
maintains the vehicle must be stopped without having to hold the brakes are applied consistently - for example when waiting at traffic lights (HOLD);
when the driver suddenly the accelerator brings the brake pads contact the brake discs light as a precaution, so that the brake pressure required can be achieved more quickly if an emergency stop;
in wet conditions applied brake light touch, without the driver noticing, to dry the brake discs.
Safety and comfort
Those who wish to do so can extend the range of assistance systems to the new SLK even with the addition of features to improve both safety and comfort:
The lighting package provides additional features lighting (active curve illumination and function of the light curves), which are activated depending on driving conditions
The option with quote PARKTRONIC Parking assist the driver when parking. Its ultrasonic sensors measure the length of the car parking passes, cockpit display gives a schematic representation of the parking maneuver recommended.
Taking into account all the qualification requirements of the institutes
In developing the new SLK, the requirements of Euro NCAP and all evaluations of global consumers have been taken into account. This has contributed to the development of the structure of the vehicle body, which follows the concepts developed and optimized in a series of detailed areas. These include, among other things, members of the reinforced structure of a new side effects and new fiber-reinforced roll.
In the case of an accident, to the front-side and satellite sensors and rollover sensors help the central control unit to predict the nature and severity of the accident. Again, additional pressure sensors in the doors and acceleration sensors in the front bumper to help detect a collision with a pedestrian.
Headbag new crash-active headrests
Security system with two-stage airbags for driver and front passenger have been improved. The new feature is headbag, which offers a rich side to side to protect the head impact. In addition, the airbag in the seat backrest to protect the upper body when a side impact. Driver and front passenger knee airbags are the same thing. Seat belts with pretensioners and belt buckle, Speed-sensitive force limiters, to serve emphasizes high safety standards of Mercedes-Benz.
Another new feature find its way to the standard equipment in 2012 SLK comes in the form of throat-PRO head restraints crash-responsive, developed by Mercedes-Benz. They assist the driver and the heads of passengers in case of rear-end collision and reduce the risk of whiplash.
An intuitive wizard
Radio and other media of entertainment is a given in today's cars, the electronic navigation systems are almost as numerous, and customers need to integrate a cell phone easily in the integrated network. To meet these requirements to the best possible way, Mercedes-Benz SLK equipped with new features in the latest generation of telematics.
The sophistication of the head unit is evident from the large color screen. This monitor is located at the top of the center console so the driver is able to see the information without taking your eyes completely off the road. It can also be easily seen by passengers.
The head units share a common interface called the "central control". In the interest of the relaxed and ergonomic operation, which is close in front of the armrest. This sophisticated, metal swivel / pressure control can move in eight directions, and can also activate additional functions or confirm by pressing or turning it. Browse through the main menus and submenus is simple and easy with the new logic of the system is fast and intuitive control.
The CPU is connected to eight speakers and a volume control sensitive to the speed of 12 km / h, increasing the volume of the radio with the vehicle speed. All units are also protected against theft by electronic transfer for the particular vehicle.
